How does it operate? The
lightweight DYNOmite absorber installs, like a prop, on most 50 Hp
outboards through 502ci stern drives. During testing, you sweep the
desired RPM range by adjusting its load valve. This controls the water
level inside the absorber - which changes its rotor’s load (like having
an adjustable RPM test tank wheel). The DYNOmite’s computer records the
resultant torque at the absorber’s housing (along with the RPM) to
calculate: Hp = Torque (in foot pounds) x RPM / 5,252. Watch the video!

Automate your testing by
installing DYNO-MAX™ with an appropriate Auto-Load Servo or Electronic
Throttle Control. This allows keyboard setting of test RPM and load.
Without special programming, you can easily create self-running engine
tests or extended-duration break-in cycles. Troubleshoot problems that
take time to show up.

DYNOmite data-acquisition electronics
eliminate manual recording or estimating power from crude
hydraulic-pressure conversion charts. The DYNOmite records true Hp,
torque, RPM, elapsed time, etc. (at up to 1,000 readings per second)
while automatically applying SAE correction factors for air temperature,
barometric pressure, and relative humidity. Results display on the
DYNOmite’s LCD and can be printed to an optional portable ASCII parallel
printer.

Direct prop-shaft mounting (by a
single technician) onto most BIA splines with the included (or optional)
adapters. System can be battery powered for outdoor yard or service call
operation, so an expensive shop-ventilation system is not needed.

Precision designed and manufactured
for strength, accuracy, and reliability. Each water absorption brake,
heavy-duty torque arm, load-valve, etc. is beautifully CNC machined from
anodized aircraft billet aluminum and heat-treated stainless steel. Even
the fasteners are stainless, for the maximum submerged corrosion
resistance.

Used by many OEM training centers and
technical schools, so many outboard and stern-drive technicians
already know how to run (and prefer using) a DYNOmite. Just owning the
DYNOmite enhances your service department’s technical image among
potential employees and customers.

Cut non-billable hours trying to
isolate intermittent problems. It is not just that troubleshooting time
is often slashed in half, your mechanics stay in the shop instead of out
hauling boats around to the lake. Customers that balk at paying for your
on-water diagnostic time willingly pay for dyno testing. With DYNO-MAX
software, you can even provide them with “before and after” power graphs
and reports, documenting the results of your service work.

One marine dealer’s experience:
“After 15 years of use and well over 3,000 pulls (some in excess of
9,000 RPM) we have not experienced a single failure with our DYNOmite
absorber. And, its light weight allows one technician to set it up and
do a pull – in less than three minutes. In contrast, our old hydraulic
dyno needed two men to wrestle with the pump, was limited to 5,000 RPM,
had regular coupler failures, and its hydraulic hose bursts were
environmental catastrophes!” – Toni Marine

Dynoing pays its own way and the
most professional marine dealers typically charge an extra premium for
all of their dynamometer diagnostic work. Besides being a great service
tool, successful service managers find that just the displaying of the
brake in their service department allows them to command the higher
labor rates, shop wide, needed to operate profitably!

*Approximate; continuous capacities depend on selected absorber and test speed.
Air-cooled absorber loads are rotor temperature dependent. Water brake power
capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 to 60 psi
for every 20 continuous Hp. Call Land & Sea, Inc. at (603) 226-3966 for the
approximate capacity of any specific test configuration.
